∙ 7y agoIn humans and other mammals, every normal body cell contains two sex chromosomes. There are two different sex chromosomes, the X-chromosome and the Y-chromosome. Females have two X sex chromosomes, having the XX genotype, and males have one X sex chromosome and one Y chromosome, having the XY genotype. When gametes (sex cells) form, the female's gametes (eggs) will each have one X sex-chromosome. Half of the male's gametes (sperm cells) will have either one X sex-chromosome or one Y sex-chromosome.
Since all eggs contain one X chromosome, and a sperm cell has either one X or Y sex-chromosome, the gender of the offspring is determined by the male's sperm. If an offspring receives an X chromosome from the father, the offspring will have the XX genotype, and will be female. If an offspring receives a Y chromosome from the father, the offspring will have the XY genotype, and will be male.

Does the sperm determine the gender of a baby?
No. The male determines the sex. A female has 2 X chromosomes, while a man has an X and a Y. A woman can only give an X, but a man can give an X or a Y, thus making the sperm cells the determining factor.

Is there a baby gender predictor one can use for telling the sex of their baby?
The only way to learn your babies gender is to wait for it to develop further so the doctor can show the mother and father the gender of the baby. There are products and superstitions that claim they can determine a babies true gender before the baby even has enough time to grow. Such things are false.
